Note that you can adjust demographic characteristics of your student body without considering that characteristic in the admission process. You can instead work very hard to get more qualified people with the desired characteristic to apply, and to get those who are accepted to pick your school instead of some other school.

Caltech did this at one time with women (I don't know how they do it now). They would seek out high school women who showed promise in math and science, and encourage them to consider Caltech. Women who were accepted would be given trips for themselves and their parents to come visit the campus where the benefits of Caltech could be pitched.
